HERBERT HJSTEELE, OF SYRACUSE, NEW YORK, ASSIGNOR TO TH E MON ARCHTYPEWRITER COMPANY, OF SYRAUUSE, NEW YORK,

A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

To all whom it may concern:

Be it known that I, HERBERT Iii/STEELE, citizen of the United States,and resident of Syracuse, in the county of Onondaga and State of NewYork, have invented certain new and useful Improvements in Type- WritingMachines, of which the following is a specification.

- My invention relates to ribbon mechanism for tv ewritin machines andits ob'ect en- P g l 7 c erally stated, is to provide means for changmgor shifting automatically at a predetermined point orpoints in the lineof writing field again operative.

' To the above and other ends the invention consists in the features ofconstruct on, com-.

binations of devicesand arrangements of parts, hereinafter fullydescribed and particularly pointed out-in the claims.

Generic claims directed to means for accom lishing the general objectabove stated will found in my a plication filed September 1st, 1906,Seria No. 332,949. In the presentiristance I accomplish the resultssought by providing two or more cooperating shifting members, one ormoreon the travel.- ing element or carriage of the machineand one on a fixedpart thereof, said members being relatively adjustable so that they mayco-act at varying redetermined points in the carriage travel.

hen two of said members co-act the ribbon mechanismis automaticallychanged or shifted to resent,- when the types are actuated, a di erentfield or portionof the width of the ribbon to the action of thctvpes andthe new ribbon field remains operative as long as the two ribbonshifting members continuein co-action- Theconstruction is such that assoon as said co-acting members disengage, the ribbon mechanismisautomaticallychanged back or. re-shifted to render thejfirst ribbonfield. again operative.

Specification of Letters Patent. Application filed September 1- 1906)SerialNo. 332351,

' Patented Feb. 11, 1908.

It will be understood that by my present construction the ribbon fieldsmay be shifted and re-shifted a plurality of times during the travel ofthecarriage' in one direction. During the return movements of thecarriage' no change or shift of the ribbon fields takes place. v 5 Mypresent invention is preferably em 'ployed in connection with tabulatingdevices so that if a two-color ribbon be used the characters in one ormore columns on the work sheet may be written in one color while thecharacters in one or more other columns variously disposed may bewritten-in another,

color.

'I have shown my invention asapplied to a Monarch front striketypewriting' machine,

which machine employs a vibratory ribbon carrier, but it is to beunderstood that said invention may be adapted to other forms of writingmachines.

In the accompanying drawings, Figure 1 is a full-sized longitudinal,vertical sectional view of a typewriting machine embodying my invention,parts of the machine being omitted and parts being broken away, thesection being taken on the line 'w.w of Fig. 2 and looking in thedirection of the arrow at said line.

F ig. 18 isa fragmentary sectional viewtaken on the plane represented by the line2-2 in Fig. 17 and looking in the direction of the arrows atsaid'line.

Referring first to Figs. land 2, the main frame of the machinecom-prises a base.1, corner posts 2 (of which one only is shown)- and atop plate 3 sn ported by said ost s.

Key levers 4 are in cru'med on a fu crnm plate 5 mounted in-the rearofthe-base, each .of said key levers being provided with a re storingspring 6. Pivoted at 7 to each key lever is a'sublever-8 slotted at itslower end portion to cooperate with a fixed abutment 9 supported at thesides of the base. The.

upper end of each sub-lever is connected by a link 10 with a type bar11, said type bar being .pivotally mounted in a hanger 12 secured by. ascrew 13 to a segmental hanger The hangers are arrangedin arcs ofcircles on the support and the free ends of the type bars 11. arenormally supported on a type rest 15, said type bars when actuatedcooperating with the front face of a rotary platen 16 mounted in aU-shaped platen frame or carriage composed of side bars 17 and a rearbar 18 connecting said side bars. The rear bar 18 is provided at its topand bottom with oppositely disposed longitudinal grooves which cooperatewith anti-friction balls 19, said balls also cooperating with fixedgrooved rails 20 secured to standards 21 rising from the top plate 3.Pivoted at 22 in the side bars of the carriage are horizontally disposeda'nd rearwardly projecting. arms 23, said arms supporting at their rearends a carriage rack 24 which normally meshes with a feed pinion 25secured to a shaft 25" journaled on a bracket 26 rising from the topplate. A toothed escapement wheel 27 is opcratively connected with saidshaft 25, and cor'iperative with. said escapement wheel are escapcmentdogs 28 mounted at the top of a vibratory carrler or rocker 29. The dogrocker 29 is provided with. a horizontally disposed and forwardlyprojecting arm 30 which is connected by a link 31 wlth a centralrearwardly extending arm 32 of the universal bar frame, said framecomprising a rock shaft 33 journaled at the sides of the base and auniversal bar proper 34 extending from side to side of the machmebeneath the series of key levers 4'. The universal bar is adapted to beoperated by any of the key levers, thereby causing the dog carrier to bevibrated and the dogs 28 to cooperate in a known manner with theescapement wheel 27 to permit the carriage to bedrawn a letterspacedistance at a time leftward across the top plate under the influence ofa spring drum'35 with which said carriage is connected by a band orstrap 36. Ribbon spools 37 (only one of which is shownin the drawings)are arranged above the top plate, one at each side of the ma- A ribbonchine and forward of the platen.

38 is wound upon the ribbon spools, said rib-.

bon as herein shown being divided longitudinally into fields a and b ofdifferent characteristics that is to say, the,field a may be,

one color-such as black and the field b' of a different color such asred, or the field a may be copying ribbon andthe field I) record.ribbon, for example. I The ribbon 38 may be fed longitndinally from'one spool to the forward end of a horizontal shaft 43', said shaft beingsupported in lugs 44 depending from the topplate and .carrying at itsrear end a' -beveled pinion 45, said pinion 45 being adapted to meshwith a beveled driving pinion 46 mountedon adriving or power shaft 47.Rotary movement is transmitted to the shaft 47 by beveled pinions 48 and49, the

pinion 48 being operatively connected with the" driving shaft and thepinion 49 with the spring dru'm 35. It will be understood that bothribbon spools are provided with like gear trains which'are adapted to beactuated by the driving pinions 46 on the shaft 47.

The driving shaft 47 is journaled in lugs 50' depending from the underside of the top plate and is capable of both rotary and longitudinalmovement in its bearings, the longitudinal position of said drivingShaft'determining which driving pinion 46 will be in mesh with itscooperating pinion 45 and which ribbon spool will be turned to windthezribbon thereon.

Midway between thc'ribbon spools the ribbon38, as best shown in Figs. 1and 3, is

threaded through a vibratory ribbon carrier or vibrator 51, saidvibrator being guided and supported in the upright arms 52 of a guidebracket 53, the latter being suitably secured to the top plate of'themachine. The stem 54 of the carrier orvibrator is slotted as shown at 55to form arms 56 which carry a cross pin 57 said cross pin being engagedby the slotted forward end of an 1 described to effect a operatmgmemberor lever 58 which has a pivot or fulcrum pin 59 'ournaled in the arms 60of a U-shaped brac et 61 depending from the underside of the top plateand fixedly secured thereto by a headed screw 62 (Figs. 2 and 14). Thefree end of' the forward arm of'the operating lever is pivotallyconnected with the vibrator and the free end of the rear arm is curledor turned back'on itself, as indicated at 63, to provide an opening theinterior of which is threaded and receives an adjustable screw stop 64which during the operation of the machine cooperates with a stop memberpresently to be one or another of the arms 60. The collar 65' iscomparatively narrow and the collar 66 comparativelywide, the latterbeing at the left of the operating lever and serving to maintain it atconsiderable distance from the left hand arm 60. Coiled around. the

collar 66 is a wire spring 67, the forward end of which is hooked aroundthe lower edge of the operating lever between the pivot of the latterand the vibrator: The rear end ofthe spring is coiled around a headedpin or stud 68 extending laterally from the upper end portion of aconnecting link 69, the lower end of the latter being pivotallyconnected at with the arm 32 of the universal bar frame,

operated the "link 69 will be drawndown ward and through the spring 67will swing the operating lever 58 on its pivots, thereby actuating theribbon vibrator. The normal position of the latter is such that, asshown in Figs. 1 and 11., it normally' maintains the ribbon below theprinting point, but when the operating lever is actuated the vibratorwill be. thrown u )ward to intcrpose the ribbon in" the path of thetype.

positive stoppage of the is madeuse of in a machine having a vibratoryribbon carrier, it is necessary to vary the limit of upward movement ofthe carrier or vibrator or movement towards the printing )oint in orderto .move one field o1 anot er of the ribbon to the printing point andinto the path of the types. In the construction shown 1 effect thisresult by providing a stop member adjustable to cooperate with the stop64 to arrest the operating lever 58 at different points in its travel.It will be apparent, however, that this is only one way of effecting thechange or shifting the ribbon field and that various other ways ofaccomplishing this result may be used within the scope of my invention.The stop member or ribbon-field-changer herein illustrated is designatedas a whole by the numeral 72 and is clearly shown in Figs. 2 and 5. Saidstop member is slidably mounted on the ribbon driving shaft 47 andcomprises a cylindrical stopping portion 73, a cylindrical stoppingportion 74 of less diameter, a hub portion 75 and a second hub portion76 at the right of the cylindrical stopping portion 73. The hub'portion75 recelves a screw 77, the innerend whereof engages in a slot 78 formedlongitudinally of the driving shaft 47, the construction being suchthat. the stop member 72 may be moved lengthwise or slid to and fro onthe driving shaft 47 but is caused. to turn with said shaft It will beapwhen the latter is rotated. parent that by moving the stop member 72lengthwise of the driving shaft one or anotherof the stopping portions73 and 74 will be brought into position to cooperate with the screw stop64 when the operating-lever is actuated by any of the keylevers, The

parts are so proportioned that when the operating lever is arrested bythe sto ping ortion 7 3 the ribbon will have been ifted ar enough tobring its top field or stripe at to the printing point only. If thestopping portion 74 is in operative position the ribbon will be liftedstill higher before the o )erating lever is arrested, thereby bringingthe lower field or stripe b to the printing point.

I provide means for automatically sliding the stop member 72 to and froon the driving shaft, said means. acting at predetermined 'points in thecarriage travel and. effecting an automatic change or shift in theribbon field at said predetermined points. In the present instance theautomatic shifting means comprises a verticallydisposed. arm 79, thelower end whereof is bifurcated, the arms 80 of the bifurcation engagingin a circumferential groove or depression 81 formed "in the hub portion76 of the stop member 72,

as shown in Figs. 1, 2 and 6. The upper end of the arm 79 is formed\\'!l'll a collar 82 perarm of the lever 93.

' The spring 105 serves normally to main forated to receive the innerend of a springpressed slide rod 83 and being fixedly secured to saidslide rod by a set screw 84. The slide rod 83 has its bearings in theright-hand lug 50 of the pair of lugs in which the driving shaft 4:7"isjournaled and in a smaller lug 85 depending from the under side of thetop plate at the left-of the ri ht hand lug 50. A collar 86 is securedto t 1e slide rod near.

its right hand end by a set screw 87 and a somewhat longer collar 88 issecured to the slide rod by a set screw 89 between the two bearing lugs50 and 85-. An expansion spring 90 is coiled around the slide rod 83between the collar 88 and the right hand lug 50, said spring tendingconstantly to press the slide rod longitudinally leftward in itsbearings. Normally the spring maintains the collar 86 in engagement withthe outer or right hand i ace of the lug 50, as shown in Fig. 2. Theparts are so proportioned that 1 normally the arm 79 at the opposite endof the slide rod is thereby positioned to mainin operative position.rear of the collar 88 is a pin or stud 91, said stud being normallyhorizontal and engaging With a slot 92 formed in the lower end portionof one arm of a shifting lever 93 fulcrumed on a headed shouldered screw94, said screw being supported in a right angle bracket 95 fixed to theunderside of the top I late by screws 96 as shown in Figs. 1 and 8.

lvoted on a shouldered screw 9.7 which is siipported in the lever 93above the fulcrum 94 of {the lever is a trip lever 98 which extendsupwardly through an' opening 99 in the top plate 3 and terminatesina'lug 100 having a straight working face 101 and a curved face 102,the details of the lever 98 being best shown in Figs. 6 and 7. The lowerarm or tail 103 of the lever 98 is provided with a rearwardly extendingpin 104 on which is fastened one end of a coiled spring 105, theopposite end of said spring being secured to a pin 106 projectingrearwardly from an extension 107 on the lower tain the arm 1030f thelever 98 in contact with the head of the screw 94 on which the lever 93is fulcrumed, the normal relation of" the two levers 93 and 98 beingbest shown in Fig. 6. As will be more clearly understood from whatfollows, said lever 98 turns together with the lever 93 on which it ismount ed to effect a' shift of the ribbon mechanism when the carriagemoves in one direction, but on the return movement of the carriage saidlever 98 is adapted to be tripped or moved relatively to the lever 93seats to yield and permit the unobstructed return of the carriagewithout afiecting the ribbon. The two levers 93 and .98 constitute atwo-part shifting device or member supported on a fixed part andcooperative-with one or more shiftmg or contact members carried by thecarriage to actuate the spring-pressed slide rod 83, and therebyautomatically position the metal and comprise side arms 109 and a connectin bottom portion 110, the me r'nber-bev ing su stantially U-shaped.Prongs or fin-' gers 1-11 and 112 project horizontally and rearwardlyfrom the side arms 109, the fingers '11 1 being above their com anionfingers 1'12 and-being cut away as in icated at 113 to enable saidfingers 1J1 to-yield or give slightly. The free lower end .of eachfinger111 terminates in aprojecting rounded por-f tion 114. Between each pairof arms 111 and 112 isa slot. or opening 115.

The member 108 is adjustably mounted on a bar or rod 116 which isrectangular in cross section and is provided transversely'of its top andbottom I notches or depressions 117,-'therebyorming sets of oppositelydis osed teeth '1'18. The

"fin'gers 111 and 112 o the stop member 109 fit into the notches 117between the teeth .118 in the bar 116, said bar being received intheopenings 115 between'the fingers. The dis tance between the rounded ends114 of the fingers 111 and the up erfaces of the oppo site fingers 112is slight y less than the thickness of the bar 116 (see Fig. 8) betweenthe notches 117, so that in order to adjust the member 108 on'the bar itis necessary to force the companion fingers 1-11 and 112 slightly apart,the fingers 111 yielding for'this purpose and springing back to normalposition when the rounded projections 114 pass out of engagement withthe notches 117, thereby locking the member 108. in place. The distancefrom the-center of one notch 117 to the next n'otch is preferably equalto one letter,

aces. with a series of 'arallel space distance and the back of the bar116 is referably provided with a scale, as shown in igs. 6, 7 and 15,corresponding in its markings to the usual platen scale of the machine.The left-hand end of. the bar 116 is reduced to form a cylindricalbearing portion 119 (Figs.v 2 and 15) which is received in a bearingopening in a curved sup orting arm 120 secured to the inner face oft eleft-hand side ba'r17 of the carriage by headed screws 121 (Figs. 1andi2). bar 116 is provided with a threaded opening 122 (Fig. 15) whichreceives the reduced threaded end 123 of a bearing stud 124'projectinglaterally leftward from the end section 125. Projecting rightward fromsaid The right-hand end of the end section is a stud 126 which receivesa finger button 127 Fig. 2), the latterbeing sebearing for theright-handportion of the bar 116, said stud 124 bearing in an opening129 (F1g.'16) formed in the lower end portion of [a supporting arm 130,said arm being secured to the inner-face of the-right-hand side bar 1.7of the carriage by headed screws 131 which pass through openings 132 intheupper end portion of the arm 130 and enter tapped holes in the sidebar 17. The lower-end portion of the supporting arm 130'is provided witha lateral offset 133 extending inwardly and providing ledges orshoulders/ 134 upon of saidbar 116 on .its longitudinal axis.

The construction is such that the bar is nor-g mally maintained in suchposition that the member or members 108 carried-by said bar willproperly cooperate with the two-part shifting member supported on thebracket 95, but by unscrewingthe end piece 125 the right-hand endportion of the bar 116 may be lifted from the shoulders 134 and the barmay then be turned on its longitudinal axis until the stop member ormembers 108 are thrown back to inoperative position ('as shown in Fig.9), it being sometimes desirable torender the automatic ribbon shiftingdevices inoperative as will be better understood from what follows.-

lt will be understood, of course, that by means of the scaleon the backof the bar 116 the member or members 108 may be adjusted relatively tothe length of. the carriage and so as to become operative at any,

predetermined point or points in the travel thereof. The twoart membercarriedby the frame is norma ly substantially upright, as shown in Fig.2, but during the'movement of the carriage a letter space direction fromleft to. right the stop member'lOS will be brought into engagement withthe working face 101 of the leveror part 98 of said two-part member andwill swing the upper arm of said lever leftward The lower arm or part103 of said lever is at thistime in engagement with the screw 94 so thatno relative movement between the'lever 98 and the lever 93 can takeplace, and in order that the upper armof the lever 98 may yield to themember 108 the lever 93 must turn on its fulcrum screw 94. During thisturning movement the upper part of the lever 98 serves in efl'ect as theupper arm of the lever 93. The lower slotted arm of the lever '93 swingsin the opposite direction about the fulrrum screw 94 and being inengagement with the stud 91 onthe slide rod 83 will slide said rodrightward. on its bearings a ainst the pressure of the spring 90. Thissliding the bar 116' is adapted to rest and which serve normallytopreventthe rotation said slide rod will remain motionless in the jposition shown in Fig. 5 while the end of the lever 98 rides over thebottom face of the part 110 and until the end of the lever passes out'of- (-vontactwith'th'e part 110. During this riding contact between thetwo stop members the parts will be in the positions illustrated in Fig.6. From an inspection of this figure it will be apparent that therightward movement of the slide rod. 83 against the influence of. thespring 90 operates through the arms 79 on the member 72 and slides saidmember rightward, moving the stop face73 pi-1t of operative position andbringing the stop face 74 into operative position, thereby automaticallyvarying the throw of the ribbon vibrator and changing the operativefield of the ribbon. As soon' as the shifting members disengage, theslide rod and connected parts will be restored from the positionshown-inFig. 5 to that shown in Fig. 2 by the operation of the spring 90,thereby bringing about a reshift-. ing of theribbon fields. The carriagemay, be moved manually from left to'right by operating the usual releasekey, thereby causing the two shifting members to cooperate as abovedescribed, and said carriage may then berestored to begin a newline .inthe usual manner; or said carriage may, of course, be moved to effect acooperation between the shifting members by the usual letter spacingoperations; In the present case, however, I prefer to employ tabulatingdevices to cause movements of the carriage when it is desired to shiftthe ribbon auto-' 'matically from one field to another, for the reasonthat such automatic shifting is preferably used in statement, manifestor other tabulatin'g work and work of this,charaeteris facilitated. bythe use of tabulating mechanism.

The tabulating mechanism shown in the present instance is substantiallythe same as that employed in the Monarch typewriting A crank arm 1.39extends horizontally and forwardly from the right hand portion of thecolumn stop bar 137, said arm 15$) being connected by link 1 10 (Figs. 1and Z) with a sub-lever 141, said sub-lever being pivoted its forwardend with a key button 148. It

Wlll be understood that when the tabulating 'ke 148 is depressed itoperates through the su -lever 141' to draw the link 140 down wardly,said link, through the crank arm' 139, effecting a vturning movement ofthe stop bar 137 in its bearings, thereby turning the column stops 136forwardly into position to arrest the carriage stop 135' when thecarriage is released, said column stops 136 being v normally in:inoperative position out of the vpath of the carrlagestopyas shown inFig. 1'.

In order to effect the release'of the carriage when the tabulating'keyis-operated an arm [1401s adjustably secured. to the link 140 inpositionto-en age,'whenl the link is drawn 151 on a bracket 152 depenunder side of the top plate. Theinner or left downward, wit the righthand arm of a release lever 150, said leverjbeingfulcrumed at ing. from-'the i hand arm of the'release leve'r150 is'connected at-153 witharelease arm or lifting member 154, said member extending upward throughanopening 1 55 in-the topplate and bifurcated at its upper end, the armsI the bifurcated. 'ortion being disposed'at the sides-of'the sha t 25and being guided on said shaft. The arms 156 are bent horizontallyforward at their upper ends to provide lifting shoes 157 said liftingshoes normally lying beneath and out of contact with-th'ecarriage feedrack 24 It will be understood that; .when the tabulating key operatedthe lever 150 will have its'right'hand arm depressed the feed pinion25,thereby rel'easing thecar- I and its left-handarm raised, thereby movingthelifting member 154 upwardly and causing the lifting shoes";15.7,toengage the rack 24 and swing said rack upward y 22 to effect adisengagement between it and ria e. The mode of operation of myinventi'on as thus far described may be"brie'fly explained;

Y The present, form of the. invention may be employed genera-ll tageousor'desirab e to write alternate -col-. umns in different colors torenderconspicuous certain items or entriesat stated intervals. In thedrawings three shifting or contact members'108 are shown mounted on thebar or rod 116 at different points in the length of thecarriage, the,right-hand member 108 being considerably longer thanthe other twomembers. It is to be understood, of course, that the number andarrangement ofithe members 108-will vary with the charactor of work to;be done and fur't'jherthat the aboutits pivot wherever it is advanwitthe width of the columns to be written. The lengths of the members 108determine how long a time in the travel of the carriage orwhatproportion of the whole extent of carriage movement particular ribbonfields will remain operative. Obviously, by-prosheet is wide, an entireline or a succession of lines may be written in one color] How- 'ever ,1prefer to effect such a result by other means to be described presently.The position of the member or members 108 on the the location of thecorrespondin column tion with the other shifting member on the frame atleast two letter spaces before the carriage stop .135 cooperates withthe colrepresenting a margin of safet for insuring the beginning ofwriting in the column in that other column stops 136 may be emtheshifting members 108, said other column sto sserving to define thecolumns which are .to a e written in. black. The black columns mayalternate with the red columns as in the character of work now-beingconsidered, but of course the arrangement of the columns will depend onthe style of the work. This feature will be referred to at length alittle later.

The column-stops 1-36 and the adjustable .shifting members 108 havingbeen properly arranged, the work sheet is next entered in the machineand fed around withthe platen in the usual manner until the properposition .is reached for writing the first line of tabulated matter. Thefirst item or portion of "the first line may then be 'written'byoperating the appropriate key levers in the usual manner, causing thecarriage to move stepby-step in letter space direction. At this theframe will be in the positions illustrated in Fig. 2/ It will beapparentthat at printing operation the ribbon vibrator 51 and its actuatingdevices, comprising the operating "lever 8 and the link 69', will bemoved from the ositions shown in Fig. 11 to those shown in Fig. 12,thereby throwing the ribbon from the normal osition illustrated in Fig.11 up.- ward until t e field a or the black field covers the printingpointand is interposed in the path of the types on the actuated typebars. From an ins ection of Fig. 12 it will be apparent that t e upwardthrow of the rib- "bon'is positively arrested by the engagement of thestop "64 on the operating lever 58 with length of said members 108- willbe varied stop or stops 136 and preferably t e members 108 arearranged-to enter into cooper-athe automatic'shifting of the ribbonprior to which thechange of ribbon fieldis to go into effect. 'It is tobe understood, of course,

Tlrereupon the main spring will. operateto draw the carriage rapidly leftward across the top plate until thetabulator stop 135 on the carriage cooperates with v the proximatecolumn sto 136. Two letter space distances prior to t e 006 erationbetween thejcarriage stop 135 an the proximate column stop the proximateshifting member 108 on the carriage'will engage with the two-partshifting member on the frame and will swing the latter from the positionshown in'Figs. 2 and 6 to that shown in Fig.

As has been already explained this operates to move the stop member 72transversely of the operating lever 58 and renders the stopping portion73 inoperative, and the sto ping portion 74 operative. The result w llbe that after the arrest of the carriage by the cooperating tabulatingstops, subsequent depressions of the printing keys will.operate to swingthe ribbon operating lever 58 from the. position shown in Fig. 11 to theposition shown in Fig. 13 wherein it will be noted that the arrest ofthe operating lever is brought about by the cooperation between the'stop64 and the stopping portion 74 on the stop member 72. Ihwill be apparentthat at this stage the ribbon during printing operations will be thrownupwardly from the position. shownin Fig. 11 to that shown in Fig. 13 tobring the lower or red stripe or field I) op osite the printing pointand. into the path of t 1e types. It is to be'noted that the greaterextent of movement of the operating lever at this stage not only servesto impart a longer throw to the vibrator but also permits a greaterdownward movement of the link 69 before the lever 58 is arrested so thatthe fiexurc or bending of the spring 67 is less than when the stoppingportion 78 of the member 72 was used.

From what has been said it will be apparent that the stopping portion 74Wlll remain operative and consequently the ribbon field I) or red fieldof the ribbon will be operative as long as the operative memher 108,moving leftward stcp-by-step as the carriage is fed during printingoperations, remains in eontactive engagement with the upper arm of thelever 98. As soon, however, as the member 108 passes to the left of thetip end of the lever 98 the compressed spring 90 serves to restore'thelever 98, the lever 93 the slide rod 83 and the stop member 72 to thefirst position illustrated in Fig. 2, thereby again renderingthestopping portion 73 operative. Consequently if the tabulatingmechanism be operated to release rapidly leftward until arrested in apredetermined columnar field which is at the left of the next member 108on the bar 116, the writing in said predetermined columnar field will bein black. ()r if without employing the tabulating mechanism, any writingbe done before said next member 108 becomes When, however, thetabulating mechanism is operated to bring said next member 108 intooperative relation with the upper arm of the lever 98, the stop member72 will be shifted in the manner heretobefore described to again renderthe lower or red field of the ribbon operative, so that the writing inthe columnar field in part defined by that column stop 136 whichcorresponds with said next member 108 will be in red. The operationsabove outlined may be continued to'the' end that the number and positionof the columns written in red will depend upon the number andarrangement of the shifting members 108. The-end of the line havingbeenreached, the usual line spacing devices may be operated and thecarriage returned from left to right by hand in the usual manner tobegin a new line of writing. During the return movement of the carriagethe various members 1.08 will engage in turn with the rounded endportion 102 of the lever 98 and will operate to trip said lever,swinging it about its fulcrum 97 and moving it relatively to the lever98 and stretching the spring 105. The position of the lever 98 while itis tripped or 1n cooperation with one of the members 108 is illustratedin Fig. 'l' which, it will be remember 116 moving with the carriage inthe direction of the arrow from right to left.

As soon as the engaged member'108 has passed to the left(as viewed in Fig. 7 of,the lever 98, the latterwill return to thenormal position shown in Fig. 6 and the carriage and cause it to ump orrun.

It will furthermore be seenthat the ribbon mechanism'will be r automatically shifted so as torender a different ribbon field operative when one of the shiftingmembers on the carriage coeperates with the two-part shifting member onthe frame; that said different ribbon field will remain operative aslong as said members remain engaged; that as soon as the two en agedmembers separate-or disengage the rib on fields will be automaticallyshifted backsothat the ribbon field which was operative in the firstplace will be again operative; that the operations above outvggolinedwill be repeated each time any following shifting members on thecarriage cooperate with the two-part member onthe frame; and that afterthe disengagement of the final member on the carriage with the member onthe frame the ribbon shiftin 1 devices will be automaticallyrestored tot e first position so that the ribbon field'firstoperative' will againbe ready for use. It will also be noted that during the return movementof 40 the carriage to begin a new line of writing the shifting member ormembers on the car riage will cooperate with ther-two-part shift ingmember'on the frame in such a way that one part of the latter'will'trioryield sothat he a teredor affected during returmmovements ofthecarriage, the consequence being-that at the beginning of the new linethe parts controlling the ribbon shift or change of field willbe in thesame relative positions that they were 7 when thep'r'eceding line wasbegun.

a It may sometimes be desirable .to write an entire line or successionof lines in a. sin le color, and referablyin order to-accomplish rovidemeans for rendering the automatic ribbon 'field shifting devicesinoperative and other means manually controlled for rendering one oranother of the ribbon fields operative at To render the automaticshifting devices inoperative it is only necessary to unscrew the endsection 125 of the bar or rod 116 and to lift the right hand end of saidbar slightly and "communicate a turning movement to the bar rear-,wardly in the direction of the arrow in Fig. 8

until the bar and the stop members 108 thereon have reached the ositionshown in Fig. 9. From an inspection of "the latter figure it will beapparent'that as the result of the turning movement, 'the members 108have been shifted to ositions where they will be inoperative on thelever 98 during the to andfro movements of the carriage and that as aconsequence the automatic shifting mechanism will not be afiected duringsaid to and fro movements.

With the members 108 inoperative, as

shown in Fig. 9, the member 72 inoperative position as shown in='Fig. 2by the spring 90facting on said stop member 72 through the slide rod 83and the arm 79 the stopping portion 73 of will normally be maintained 7thereon and that conse uently the upper or black field a of the rib onwill be operative. Whenever it is desired to make use of the red ribbonfield, the stop member 72 may be manually shifted transversely of theoperating lever 58 by means now to be described. As shown-in Fig. 2 arodor bar 158 is screwed or otherwise secured in the righthand end of theslide rod '83, said rod 158 being of less diameter than the slide rod.The right-hand end portion of the rod 158 extends through an opening orslot 159 formed in the right-hand side plate 160 of the machine for thepassage therethrough of the righthand end portion of the ribbon drivingshaft 47 (Figs. 2 and 4). Outside of the side plate 160 the end ortionof the rod 158 has secured to it a nurled finger button 161. Normally orwhen the black field a of the ribbon is operative, the finger button 161stands close to the side late 160, as shownin fulllines in Figx2. otheleft of the side plate the rod 158 is provided with a circumferentialgroove 162 which is adapted to coo erate with a key hole slot 163 formedin j a ocking plate 164 which is slidably mounted on the inner face'ofthe side plate 160. The locking plate 16a is provided with elongatedslots 165 which receive small' headed "screws 166, said screws enteringtapped holes in the side plate 1601 The construction is such that'thelockingjplate may.

belslid fore and aft of the ma e on the shanks of the screws 166 to oneposition or another when the groove 162 is in register therewith andwill be frictionally retained in adjusted position between the underside of the heads of said screws and the inner face of the side plate160. i

The forward end portion plate 164 is bent laterally ri htward at rightangles to the body of the loc ing plate to provi e a handle or fingerpiece 167 by which said locking plate may be manipulated, said handleprojecting through a cut-away or slot 168- formed in said side plate.mally or when the black field of the ribbon is operative the rod 158passes through the of the locking Norlarger end of the key hole slot 163as shown in Fi 4:, the dimensions of the larger end of said s ot beingsuch that the to and fro movements of the rod 158 when the automaticribbon shifting devices are operated are not interfered with. When, asis now being considered, the automatic ribbon shifting devices areinoperative and it is desired to use the lower or red field of theribbon, the finger button 161 is ulled to the right to the dotted lineposition Fig. 2) to overcome the spring 90 and draw the slide rod 83 andthe stop member 72 rightward until the stopping portion 74 of said stopmember is in position to cooperate with the stop 64 onthe operatinglever 5.8... The rightward longitudinal move- '-ment of the rod 15.8brings the circumferenand the mem tial. groove 162 into the plane of thelocking plate 164 so that the operator, still maintaining the fingerbutton 161 in the dotted line osition, may push the handle 167 of theocking 1plate rearwardly, causing the narrow end of t e key hole slot163 to cooperate with the groove 126. The width of the narrow end of thekey hole slot 163 is slightly greater than the reduced part 162 of therod 158 within the groove 162, but the width of said 1 narrow portion ofthe key hole slot is not so great as the diameter of the rod 158 outsidethe groove. Conse uently the finger button 161 may now be re eased andthe tendency of the spring 90 to restore the parts to the position shownin Fig. 2 will be prevented by the engagement of the right-hand wall ofthe groove 162 with the portions of the right-hand ace of the lockingplate 164 which are above and below the narrow end of the key hole slot163. It will be apparent, therefore, that'as long as the locking plateremains in its rearmost position the-slide rod 83 will be locked so asto maintain the stopping portion 7 4 of the stop member 72 in operativeposition,

and that the red field of the ribbon in conseuence may be used to anydesired extent. hen it is desired to again use the black field thehandle 167 may be pulled forward, permitting the spring 90 to restorethe slide rod er 72 to the positions shown in Fig. 2. When. it is againdesired to make use of the automatic shiftin mechanism the operator mayturn back t e-bar 116 from the a position shown in Fig. 9 to that shownin Fig.-

8, care being taken of course that the locking plate 164 is in itsforward position.

A modified construction of manual shifting mechanism which maybeemployed in lieu of the. grooved rod 158 and the-locking plate 164 isillustrated in Figs. 17 and 18.

The slide plate 173 ispivotally connected by a double headed pin or loose rivet 17 7 with acurved link 178 which extends forwardly beneath the top plate and 180,said lever being fulcrumed-on a shouldered screw 181 which enters theunderside plate, passing through a boss or s acing s eeve'182 andserving to maintain t e hub 180 of the lever 180 close against saidboss. The outer or free end of the lever 180 extends laterally beyondthe side edge of the top plate of the machine and is provided with ahandle or finger piece 183 by which it may be manipulated to shift theslide plate 17 3 fore and aft on its bearing screws 1.75.

From an inspection of Fig. 17 it will be noted that the slots 171 and172 are angularly disposed. to each other and are connected .at theirends. During the normal automatic operation of the mechanism in a themanner previously described the slide .rod 83 will be longitudinallyreciprocated and the in or stud 170 thereon will be moved When it isdesired to dispense with'the automatic ribbon shifting mechanism the bar116 will be turned in the manner previously described to render themembers 108 inoperative on the The handle 183 on the lever 180 may thenbe pulled forward, sliding the plate 173 rearwardly and causing the pin170 to enter the slot 172, the edge of said slot serving to force saidpin and'with. it the slide rod 83 rightwardly until the pin enters theforward end portion 1.72%01 the slot 17 2, when the stopping portion.741 of the stop member 72 will be rendered operative, said stop member,as has been previously explained, being controlled by the movement ofthe slide rod 83. When it is desired to dispense with the modified.manual shitting field changing devices automatically, the handle 183maybe pushed backwardly to the first position and the bar 116 turnedover from the position shown in Fig. 9 to that shown in Fig. 8, and itwill again. bring the slot 171. into position to coi'iperate with thepin 170. i
